The old work-around, to use -demuxer lavf -nocorrect-pts does not work anymore, the two working options now are: -demuxer lavf -correct-pts and -demuxer mpegts -nocorrect-pts (note that correct-pts is default for demuxer lavf and nocorrect-pts default for the native demuxer, so there should be no need to explicitly mention correct-pts on the command line).
Thanks for this update. I'm amazed it took so long to be properly fixed but the important thing is that it finally is. Now hopefully package maintainers will update as that's a significant change which affects a LOT of users.
